OM System's compact PRO telephoto zoom — 80-300mm equiv at constant f/4 with weather sealing and lightweight design.
The OM System M.Zuiko Digital ED 40-150mm f/4 PRO launched in 2022 as a compact, lightweight alternative to the 40-150mm f/2.8 PRO. Covering 80-300mm equivalent at constant f/4, it provides PRO-series quality in a remarkably small package.
Optically excellent — sharp across the frame with PRO-series quality. Constant f/4 aperture maintains consistent exposure. MSC motor provides fast, quiet AF. The smaller, lighter design makes it ideal for travel and hiking where the f/2.8 version is too heavy.
Micro Four Thirds mount with 62mm filter thread. Weighs just 382g — significantly lighter than the 40-150mm f/2.8 at 880g. Full weather sealing and freeze-proofing to -10°C. Minimum focus distance 70cm. 1.4x teleconverter compatible for 56-210mm f/5.6.
Available used at mid-range prices. The weight savings over the f/2.8 version are dramatic — nearly 500g lighter. Check for dust despite weather sealing. The 40-150mm f/2.8 PRO is faster and sharper but much heavier. Outstanding for travel and outdoor photography on MFT.
